Title: Pressure welding wedged metal bars
IPC: B23K20/02
Filed: 1978-11-14
Abstract: A process for pressure welding two metal bars together by their ends, comprising bringing together the ends to be welded (9, 10) the ends being in a wedge-shaped form and at a temperature below the melting temperature of the metal of the bars or below the lower melting temperature if the metals of the bars are different; pressing both ends (9, 10) together in the longitudinal direction of the bars with the edges (17, 18) of the wedges at an angle with respect to one another so that the ends (9, 10) penetrate into each other without exposing the bars to a buckling load, and continuing to press both ends into each other until all of the surface material (19, 20) of both wedges is expelled out of the cross-sectional shape of the bars. The temperature is preferably a maximum of 450 DEG C below the melting point. The expelled metal may be removed by an annular cutter. <IMAGE>

Title: A circuit arrangement for producing selectable keying ratios
IPC: H03K5/04
Filed: 1979-03-12
Abstract: A circuit for producing an output signal having a selectable mark/space ratio has a multi-stage divider circuit connected to a clock on pulse generator, the last output of the divider circuit resetting a flip- flop 4 emitting the output signal, the setting input of the flip-flop being selectively connectable to any of the stages of the divider circuit. The selection means may be a selector switch 3 via which divider stage outputs a-m are selectively connectable to the S-input of flip-flop 4. In another embodiment (Fig. 3) the selection is made digitally. The circuit is employed to control the energy input to an electric heater, e.g. a cooker. The divider, operating at a slower rate using a prescaler, may also be used to time an initial full heating period. <IMAGE>

Title: Temperature control in hot strip mill
IPC: B21B37/00
Filed: 1980-09-09
Abstract: A method for controlling the temperature of a workpiece in a hot strip mill includes calculating temperature changes of the strip at each mill stand location by determining changes in workpiece deformation resistance and correlating the changes in deformation resistance to changes in temperature. Error corrections are made for changes in rolling speed. The calculated temperature change at each mill stand is used to control water sprays positioned adjacent the mill stands. A temperature sensor is placed downstream of the last mill stand to act as a check on the desired delivery temperature of the workpiece. Temperature discrepancies from the temperature sensor are fed upstream to modify temperature corrections. <IMAGE>

Title: Image reproduction method and apparatus
IPC: H04N1/409
Filed: 1982-01-27
Abstract: A method of preventing the reproduction of a defect in an area (74) of an image comprises comparing pixel values in a region (A0) of the said area outside a defect-containing region (72) to ascertain the range of the values of picture elements in a defect-free line or region in the neighbourhood of the defect-containing region. Next image values for picture elements in a portion (A1) of the defect-containing region are compared with the said range of values to ascertain whether any such picture element has a value differing sharply from the said range of values. Any sharply differing value is automatically replaced either by the value of a neighbouring picture element in the defect- free line or region, or by the average value of a group of neighbouring picture elements in the defect-free line or region, or by values having a similar mean value and similar variation to those in the neighbouring defect-free region. Then the values of other picture elements in the defect-containing region are examined and those values which differ sharply from the said range of values are automatically replaced. The defect-containing region is progressively corrected in this way, preferably working from the boundary inwards (A1, A2, A3, A4) and preferably from each side (A, B, C, D) of a rectangle in turn. <IMAGE>

Title: Earth fault indicating device
IPC: G08B5/34
Filed: 1982-04-28
Abstract: A mask is movable between a first position (Figures 1 and 3) in which it occludes an indicator (14), a second position (Figure 4) in which it exposes part of the indicator and a third position (Figure 5) in which it fully exposes the indicator. A latch (16) having arms (17) and (18) normally holds the mask in its first position in which an abutment (15b) on the mask engages a finger (18a). When excess current is induced in a current phase supply an operating coil (11) is energised and moves the latch so that the mask moves to its second position in which an abutment (15a) on the mask engages a finger (18b) on the arm (18). When the supply is isolated to clear the fault the coil (11) is de- energised, the latch returns to its initial position and the mask moves to its third position. A reset coil (12) returns the mask to its first position on restoration of the supply and after a time delay imposed by a delay circuit (13). <IMAGE>
